Enjoyed our stay here (for a month). Literally across the street from Chatuchak weekend market which is a must. The immediate neighborhood is a bit slow outside of the weekend, but Ari is very close with lots of restaurant and bar options. Also, BTS is just a 7 min walk.
The apartment is compact, but very clean (seems new), and with good quality furniture/linens etc.
Host was super friendly and quick to respond to any questions.
